本篇是根据GopherConSG2019“UnderstandingAllocations”演讲的学习笔记。UnderstandingAllocations:theStackandtheHeap-GopherConSG2019-YouTube理解分配：栈和堆你的程序中有两种内存，栈内存和堆内存。go中，每个go程都会有一个栈空间，整个程序有一个堆空间。变量是在栈还是堆上负责堆垃圾回收的GC会导致整个程序的延迟，而不仅仅是创建垃圾的部分。你可能会担心你的代码在堆中产生了多少垃圾。什么时候需要优化要有benchmarks基准来证明你的程序不够快（有大量的堆内存分配），够快就不用多此一举了。你要先确
